Thanks for the report.
I can reproduce this on macOS 14.0 (OCLP).
emacs-28, HEAD:
"--- files: 61, delta: 3.086468"
"--- files: 61, delta: 3.106478"
"--- files: 61, delta: 3.325344"
emacs-29, HEAD:
"--- files: 61, delta: 5.052421"
"--- files: 61, delta: 5.068663"
"--- files: 61, delta: 5.110502"
FWIW, master
"--- files: 61, delta: 5.124109"
"--- files: 61, delta: 5.101217"
"--- files: 61, delta: 5.13068"
